Using the given function for life expectancy of female whose current age is x years old, the life expectancy of a female whose curreny age is 65 is \(f(65)=0.0069502(65)^2-1.6357(65)+93.76\)

\(=29.364595-106.3205+93.76\)

\(\approx16.8 \) years
The life expectancy of a female whose current age is 75 is

\(f(75)=0.0069502(75)^2-1.6357(75)+93.76\)

\(=39.094875-122.6775+93.76\)

\(\approx10.2\) years

In 2000, the life expectancy of females born in certain country was 79.9 years. In 2005, it was 82.1 years. Let E(t) represent the life expectancy and t the number of years after 2000. Assume that a constant rate of change exists for the model formed.
a) Find a linear function that fits the data.
b) Use the function of part (a) to predict the life expectancy of females in 2020.
a) Let E(t) represent the life expectancy and t the number of years after 2000. Write the linear function.
\(\displaystyle{E}{\left({t}\right)}=?\)
b) The predicted life expectancy of females in 2020 is ?
